Preguntas frecuentes sobre Wooden pools

What ground requirements must be met to install a wooden pool?

A wooden pool requires a smooth, firm, and rigid base, preferably a reinforced concrete slab between 15 and 20 centimeters thick. The weight of the water distributed across the pool shell cannot tolerate slopes greater than two millimeters per meter or soft ground.

Installing the structure directly on topsoil, grass, or sand causes uneven settling that damages the tongue-and-groove joints and tears the inner liner. You need to plan for:

Level and compact the excavation before pouring the concrete.
Welded steel mesh to prevent cracks in the concrete base.
Geotextile mat between the concrete base and the liner to cushion footsteps.

Following these foundation guidelines preserves the structural integrity of the planks throughout the installation's service life.

I want to install a wooden pool on sloping ground and don't know if I can partially bury it. What should I keep in mind?

Weather-treated wooden pool structures allow for above-ground, semi-inground, or fully inground configurations, depending on the slope of the land. For any installation below ground level, it is essential to create a perimeter wall or gravel drainage barrier with a dimpled polyethylene membrane, such as Delta, to prevent damp soil from directly contacting the outer timbers.

Solid wood certified for use in class IV withstands ambient humidity, but a lack of drainage and the pressure of unretained soil compromise structural stability. Adding a lower drainage pipe connected to a drainage well ensures the removal of groundwater or rainwater. If you need adapted return or suction fittings, a kit such as the Skimmer + AR100 return jet lets you equip the pool shell with watertight built-in fittings.

What is the difference between authentic wood pools and wood-effect sheet metal pools?

The fundamental difference lies in the construction material, thermal insulation, and structural durability against touch and harsh weather conditions. Authentic wood pools are made from solid pressure-treated pine planks, providing density and rigidity that naturally maintain the water temperature much better than galvanized steel sheet structures.

Wood-effect screen-printed steel models have a thin lacquered steel wall. Although they are quicker to install above ground, they cannot be partially buried with the same structural strength. Solid wood that has aged in a controlled manner can be sanded or treated with specific oils, providing a premium finish that withstands accidental impacts without denting or losing structural rigidity.

I’ve installed a wooden pool and am concerned about keeping the water clean without damaging the boards. What filtration equipment do you recommend?

A sand filtration system with a pump sized to the exact pool volume is the right technical solution for continuously maintaining the water in wooden pools. For medium-sized pools of up to thirty cubic meters, a monobloc unit such as the Star 300 sand filter with pump provides enough flow to circulate the water four times a day without exceeding operating pressures.

Chemical disinfectants should not come into direct contact with the boards or be placed on the bottom in tablet form, to prevent the PVC lining from bleaching. Mechanical filtration, combined with floating dispensers or in-line systems, keeps the water crystal clear and prevents continuous overflows from unnecessarily saturating the surrounding wood.

What maintenance does pressure-treated wood around a pool require?

Class IV pressure-treated wood does not rot due to the biological action of fungi or insects, but it does suffer surface aging and color loss from ultraviolet radiation. This vacuum treatment introduces copper salts into the core of the plant fibers, making the wood rot-resistant for decades.

To preserve the original warm tone and prevent splinters on the surrounding decking, we recommend following this annual routine:

Clean the surface with moderately pressurized water and neutral soap at the start of spring.
Apply an open-pore wood preservative, such as a saturator or water-based stain, twice a year.
Inspect the stainless steel screws and joint profiles to fix any looseness caused by natural shrinkage.

Do not apply sealed synthetic varnishes or enamels that prevent the planks from breathing naturally.

I have small children at home and want to know whether a wooden pool structure is safe against access-related accidents.

The solid walls of a wooden pool provide a rigid vertical barrier between 120 and 146 centimeters high that prevents accidental falls from outside. Unlike conventional in-ground pools that are level with the ground, access requires actively using a removable outer ladder with raised steps.

Many manufacturers include hinged or removable wooden outer ladders that can be taken away when no adults are supervising. A supplementary stainless steel ladder is installed inside and attached to the wooden top rail. This perimeter height prevents small children or pets from inadvertently reaching the water, providing natural passive protection without the need for additional fencing.

How do you protect a wooden pool during the winter months?

During winter, never completely empty a wooden pool, as the water's weight balances ground pressure and prevents the wood from shrinking excessively due to dehydration. The right procedure combines chemical winterization with physical insulation of the water's surface.

To protect the pool during the off-season, just follow these steps:

Adjust the pH to between 7.2 and 7.4 and add a liquid winterizing chemical.
Lower the water level a few centimeters below the return outlets and skimmers.
Install a taut, waterproof cover such as the Winter cover for 4x3-meter pools to block photosynthesis and falling leaves.
Place expansion floats on the surface to absorb ice pressure in areas with severe frost.

Keeping the pool full and sealed preserves both the liner and the solid wood structural components, keeping them ready for the new season.
